Udrih was apparently hurt in the second quarter of Miami’s win over Indiana on Monday night. Udrih was limping slightly right before he was taken out of the game and X-rays performed that night were negative. But an MRI on Tuesday showed the need for surgery, which — barring a move — would leave Miami with 10 players available.

Chris Bosh is out while he deals with a blood clot, Tyler Johnson could miss the remainder of the season because of shoulder surgery and the Heat have two open roster spots after a series of trades helped them get under the luxury tax threshold. Miami has enough room below the tax line to add a player, though may have to wait a bit longer in order to avoid going back into taxpayer territory.

Udrih was acquired in a trade from Memphis earlier this season. He averaged 4.4 points and 2.5 assists in 36 games with the Heat, primarily as the backup to starting point guard Goran Dragic.
